Reducing vxfs file system without OnlineJFS

[MikeL_4]

What steps need to be followed to the file system and Logical Volume size of a VxFS file system on a server that is not running OnlineJFS ?

Also will the data for the file system have to be restored ??

[Pete Randall · Accepted solution]

1. Backup the data
2. Run lvreduce to shrink the logical volume
3. Run newfs to create the apprpriately sized file system
4. Restore the data

Agree with Pete, just want to mention that you need to "umount" the file system if you want to reduce the size of mounted file system. Without OnlineJFS, you have to reduce the size of a file system / logical volume off line.

You may have a chance to keep the data on a shrinked logical volume but it is not guaranteed according to lvreduce manpage. So, even with OnlineJFS, always make a backup before run lvreduce.
